I'm glad you could make it :)

Hah, I filed that bug on Class::XSAccessor which you mention hitting..
BTW, as I recall, the "fix" leads to a memory leak, but only during the 
end of your application - so as long as you're never exiting, or never 
in a long-running Perl interpreter, you don't notice it.
But mod_perl was the example that might get affected; I never looked 
into it further though.

I'd be interested in talks on:
* Varnish and VCL
* geographic DNS and what you can do with it;
* Your experiences with Plack, perhaps something about how to scale it up?
